Formula required to work out clients that spent in previous years but are not spending now

[becky334]

I have a spreadsheet with 4 separate tabs. Each tab has a list of clients and the amount of turnover generated from that client in that year. Tabs are 2012, 2013, 2014 and 2015. I want to know if there is a formula or way in excel of easily finding out what clients that were spending money in 2012/3/4 are no longer spending money in 2015. Any ideas please? Could I use a version of a vlookup formula?

Hi,

The first thing I'd do is get all your data onto a single sheet. Its a common mistake to start out by breaking data into separate sheets for stuff like years, weeks, departments, countries...etc. It seems a natural thing to do but in fact it just complicates things when you want to analyse your data.

Stack your yearly data records underneath each other on a single sheet and add an extra column to hold the year for each record.

When you've done that post back and upload the workbook and no doubt we can help you further.
